FUEL-B RIQUET.

' combustion and a moisture repelling :sub-

stance for preventing the absorption of water when the briquets are exposed to the elements, and which also assists the binderin holding the materials in a compact body while in transit and durin combustion.

For the purpose intent ed, the following materials are used in or about the proportions given, viz: 1

(oat waste- 90 parts Cotton seed meal 5 parts (attle dung' lpart Flint rock (ground fine)- 3 parts Coal oil residuum or as-' phaltum .1 part The coal, which maybe lignite, or any waste coal from mines is ground to powder before using and then the cotton seed meal, cattle dung, ground flint rock and coal oil residuum are added and the whole heated and thoroughly mixed, lifter which the composition is subjected to pressure in fnolds to form briquets of convenient sizes for 'use under Various conditions.

In connection with cotton seed meal and coal oil residuum, all kinds of waste coal may be manufactured into briquets and will burn well, and with'the addition of cattle dung, an excellent binder is formed which holds the ground coal compact and as easily-' transported and handled as anthracite coal, and in addition the briquets will not cake while burning. All the binding materials I l l l i I SPBCifiCLfiLU of Letters Patina Patented. March 10, 1908. Application filed June a, 1907. Serial n8. SIT/A38. i

are combustible and will leaveiittle ash; the" cotton seed meal and oil residuum prevent waterpenetrating the briquets to disentegrate them. Mixing fine flint rock with the above named ingredients retards combustion and therefore conserves the product. The heat absorbed by the flint rock to raise it to incandescence while the briquets are burning is afterwards radiated. when the combustible substances have been destroyed.

If found desirable the cattle dung may be I left out and the proportion of cotton seed meal increased, but where cattle dung can be obtained it is a desirable in redient.

Also, asphaltum maybe substitute for the 7 coal oil residuum where the latter cannot be had or the price is prohibitive.

The proportion of parts are given as In summer v or warm weather as haltum may be used in: l

closely as possible, for, it must be remem- 'bered, different kinds of coal waste do not 'all requ re the same amount of bind material; for instance, bituminous coa waste conta ns within itself a certain pro ortion of binding substance and will, there ore,

need less. artificial binding materiah while proportion of binder must be added to produce' serviceable and erfect briquets.

- Having thus descri ed the invention what is claimed is:

A briquet composed of the followin in 80' vwith lignite and some other coals, a greater 3 i three parts; and coal oi residuum' or asphaltum, one part. In testimony that I claim the foregoing as my own, I have hereto affixed my signature 5 in the presence of two witnesses.
